I doubt she does that for absolutely everyone, we just all got our limits. At least King never promised that he'd be a champion of LGBT rights,
like Romney once promised. MLK was also, obviously, a black man in a time before the LGBT movement really got on a roll, and even if he was around today and still had those views, its really up to black people to critique their leaders for this kind of thing, not white people. Romney, obviously, is white, Ape is certainly in her right to collect our trash.
Plus, there's nothing redeemable about Romney's position, other than "it could be worse"!
